Siege of Fort Oswego

The Siege of Fort Oswego (1757) was a battle of the French and Indian War that occurred when the 1,390-strong colonial army of William Johnson laid siege to the French fort of Fort Oswego in upstate New York, facing a garrison of 1,092 French troops and Native American allies under Theo Neville. The colonial army stormed the fort with 487 losses, inflicting 849 losses on the defenders. Neville's army was forced to withdraw from the safety of the fort as the British took it over, clearing the way for their advance towards Fort Carillon.
